1. 1

    Look into the mirror together. Raise a right hand and notice the reflection raises the hand on the same side.

  2. 2

    Hold the letter card in front of the mirror: 'The mirror shows it backward.'

  3. 3

    Darken a corner. Shine the flashlight onto the mirror and find the spot of light on the wall.

  4. 4

    Tilt the mirror slowly and watch the spot move. Invite the child to aim it at a chosen place.

  5. 5

    Test each object in the basket: 'Can I see myself? Does it bounce the light?'

  6. 6

    Sort into 'reflects clearly' and 'does not reflect clearly'.

What catches the child’s eye

  • The spot of light darting across the wall with a tiny tilt of the mirror
  • A single toy turning into many copies between two mirrors

Extensions, easiest to hardest

  1. Stand two mirrors together like an open book with a toy between and count the copies
  2. Look at the front and back of a spoon and compare the reflections
  3. Write a short name backward so it reads correctly in the mirror
  4. Look for reflections in puddles and windows outside

Control of error

The mirror and the light show the result: the spot lands where it is aimed or not, and the child can see whether a surface shows a clear picture.

Ready to move on when the child…

  • Aims the light spot at a target
  • Says that a mirror bounces light back
  • Sorts the materials correctly

Guide note

Use acrylic mirrors only, never glass. Children never reflect sunlight or a flashlight into anyone's eyes.

Try “pink tower”, “tummy”, “diaper”, “grace and courtesy”, or “October”.
